CHARLES H. PAYNE, OF CINCINNATI, OHIO.

COLLAPSIBLE TUBE.

T 0 all whom it may concern:

Be it known that I, CHARLES H.. PAYNE, a citizen of the United States, residing at the city of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Collapsible Tubes, of which the following is a specification.

My invention relates more particularly to collapsible tubes employed for distributing pastes, adhesives, olntments, tooth pastes and the like and relates more essentially to the distributing mouth or nozzle at the end of the tube through which the contents are forced. In the tubes now in use, belonging to this class, the -mouth ends or nozzles are contracted in form andare not large, and of a shape which allows the contents to come out in a rounded, oval or bulk form, rendering it practically imposient, uniform, continuous and satisfactory manner; then again in some of these tube mouths, closure devices are used to cutoff the supply by inserting said closure devices into said mouth; the peculiar form of the mouth and the closure device render it impossible to properly lock or seal said mouth without part of the contents in the mouth oozing out of the tube by the device being forced home; thus a plastic or hard deposit or crust is formed around the mouth rendering the same unsanitary and making it inconvenient and disagreeable for the user to again operate the tube.

The object of my invention is to produce a tube of this character which shall be cheap of manufacture, simple in construction and 7 highly eflicient in use, and which will overcome and obviate the objections incident to tubes of this character now in use, and thus produce an article ofgreat utility in this class.

The essential features of my invention consists in making the mouth materially wide and very thin, so that the mouth orifice. itself will be narrow and elongated, thus enabling me to press therefrom a thin, wide path of the contents (when paste is used for example), upon the article to be pasted or upon'which adhesives are to be placed; it also enables me to make this line continuous as the pressure exerted on the tube will force the contents out over the entire area of the mouth, so that the contents Specification of Letters Patent.

is placed in the mouth to close it. P The mouth being so narrow and wide, the closure fits in snugly and there is no chance for any of the contents to ooze out, thus forming a sanitary mouth end for tubes and one which is not inconvenient for the operator when he reuses the tube.

The various features and advantages of my invention will readily become apparent from the following specification.

In the accompanying drawing forming a part-of this specification:

F ig. 1, is a view in elevation of the collapsible tube containing my invention,

Fig. 2, is a similar view to that shown in fig- 1, the tube being partially broken away and the mouth end being taken looking at one of the side edges of said mouth,

Fig. 3, is an isometric view of the tube partially broken away with the closure omitted from the mouth,

Fig. 4, is a side view of the closure tube device, and part of the tube being shown in dotted lines,

Fig. 5, is an end view of the closure device,

Fig. 6, is a view similar tothat shown in Fig. 3, except that the mouth piece has a beveled side edge, and

Fig. 7, is a side view of a used by me.

In the drawing. 1. is a collapsible tube, which may be of any form or contour. At one end of this tube, I place the narrow mouth piece 2 having a long narrow mouth 3; the mouth piece 2 is of a rectangular form and extends'approximately across the entire end of the tube and the mouth 3 may be even and uniform as shown in Fig. 6; in fact, the mouth piece and the mouth may be of any desired contour, so long as said parts are narrow and wide. The mouth piece, in the present instance, is formed of two sides 5 and the'ends 10,'which are usually made integral with the head 15 of-the tube. The mouth 3 is closed. by the closure device shown in Figs. 4 and 7 and preferably made of thin sheet metal and formed of a body part and finger hold 2l' generally made of the contents of the tube 1 has been used .as desired, the body part 20 of the closure device is inserted into the narrow mouth 3 of the mouth piece 2 until its finger hold 2 lies flush oven the mouth, if the device shown in Figs. 4 and 5 is used, the clips 22 pass over the sides 5 of the mouthpiece and impinge against the same to assist in retaining the closure device in position.

It will be noted that the wide mouth, coming close to the edge of the tube head 15 -makes this part of the device more essential and handy in reaching into corners and places outside of a straight line; also allows me to lay a broader surface of paste at one sweep, therefore faster in operation and also enables me to spread the paste smoother and thinner than if a contracted narrow mouth piece isused or one which is rounded' or oval. The long thin slot or mouth effects a very economical distribution of the paste and makes even distribution over the surface more rapidly than if the paste were dumped in one spot.

The walls though which the slot or mouth is made being thin and the mouth very narrow, makes it possible to insert the flat closure device or tongue into the slot or mouth without releasing any of the contents to the outside to harden and obstruct the use of the tube.

If desired, I may place a recess 30 in the body part 20 at the bottom of the closure device; this enables me to place this recessed end over the mouth pa'rt to scrape and clean the sides of said mouth whenever needed, (see particularly Fig.4).

\Vhile I have referred to this tube as a paste distributor more particularly, it may be noted that the same can be used equally as well in connection with the use of tooth paste, ointments and the like, and its contour and specific construction may be somewhat modified.

What I claim as new and my invention and desire to secure by Letters Patent is:

1. A collapsible tube provided with a nar-,

row wide mouth and a detachable wide thin closure device stamped out of sheet metal for said mouth.

2. A collapsible tube having a narrow widened mouth part provided with a thin wide slot, and a closure device for fitting said slot and being recessed at the bottom for the purposes-set forth.

In testimony whereof, I afiix my signature at Cincinnati, Ohio, this 4th d'ay of April, 1921.
